To all whom it may concern/.

Be it known that I, FREDERICK WILLIAM RUDOLPH YAGER, a citizen of the United States of America, and a resident of Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Machinery for Making Metal Binding- Strips, of which the following is a specification.

Reference will be had to the accompanying drawings, in which-- Figure 1 is an end elevation of the machine. Fig. 2 is a view looking in the direction of the arrow 2 of Fig. 1. Fig. 3 is a vertical sectional view of the machine. Fig. 4 is a view looking in the direction of arrow 4, Fig. 3. Fig. 5 is a detailed sectional View of the parts which act upon the metal strip. Fig. 6 is a View similar to Fig. 5 with the parts in a different position. Figs. 7 and 8 are detailed views of parts that, will be described later. Figs. 9 and 10 are detailed sectional views similar to Figs. 5 and 6 with the parts in a different position. Figs. 11, 12, and 13 are details of parts that will be described later. Fig. 14 is a perspective View of a finished strip, the product of the machine.

The machine is designed to make the metal strip Y, such as is shown in Fig. 14:, continuously and automatically from a flat sheet M of metal that is fed into the machine.

The strips are used for binding calendars and the edges of pictures or for any other analogous purpose.

The object of this machine is to produce the above-described metal strip in the simplest and most economical manner possible and by devices entirely automatic in all of the operations.

The invention consists of the devices and combinations set forth in the claims.

The machine is provided with any suitable frame F, to which there is fixed the table T. The table T is mounted at an incline sufficient to cause the plate of metal M from which the strips are cut to slide down by force of gravity against the stops provided to catch it, thereby producing an automatic gravity feed of the metal plate M from which the strips are out. In place of the gravity feed an automatic positive feed may be introduced that will perform the same function. The plate M slides down and is arrested by the stops S, Fig. 10, which are so adjusted as to allow the proper projection of the plate over the edge of a shear-blade K, which is fixed to table T. A movable blade K, mounted in suitable guideways in the machine, coacts Wit-h the blade K and severs a strip from the sheet the Width required, and a clamping-bar O clamps the sheet during the cutting. The stops S and the shear-blade K are connected to same actuating mechanism, and as the shear-blade descends the stops also descend, carrying with them the severed strip, until these stops S are drawn below the surface of the platen P, which then receives the severed strip. The platen P is also on an incline sufficient to cause the severed strip to slide downward away from the shearing devices by gravity; but to insure such sliding I provide fingers K Fig. 5, which move suddenly outward at the proper instant and shoot the strips downward along the surface of the platen. Along the center of the surface of the platen P there is provided a series of stops S which catch the strip as it descends from the shear and arrest it momentarily until the completion of the bending and the ejectment of the strip which preceded it, whereupon the stops S are automatically withdrawn, and the strip again descends by gravity against the stop G, Fig. 6, which arrests the strip in the proper position for bending, and when so arrested the clamping-blade B is actuated to clamp the strip firmly against the lower edge of the platen P, and upon the completion of this clamping the stop G is lifted upward to position shown in Fig. 9, and the bender B is actuated to rock over and bend the strip to the desired form, after which the parts return to their normal position and the completed strip Y is discharged from them by gravity, as will be seen by Fig. 10.

The parts hereinbefore described may be of any suitable form or construction adapted to perform the function of cutting and bending The stops S are pivotally fixed to the bar S attached at the points S to the rods K which are connected to the eccentrics K on the cam-shaft D, which is the main drivingshaft of the machine and is driven by a pulley W through the medium of a clutch W, actuated by the rod W connected to a rocker shaft W provided with handles W which permits the operator to engage and disengage the driving power from either end of the machine.

The shearblade K is connected by the blocks K to rods K driven by the eccentrics K as described.

The clamping-bar O is fixed to blocks C, connected to the levers O fixed on the shaft 0 and is actuated by the spring C mounted at the end of the machine, and the bar is withdrawn by means of the cam 0 connected to the shaft C through the medium of the cam-roller 0, arm 0 rod C and arm (3.

The kicker-fingers K are mounted upon a bar R, which is pivoted at its ends in the frame of the machine and is actuated by a cam R through the medium of a cam-roller R arm R and rod R connected to the rod R by the lever R There is a spring upon the head of rod R to permit of the elastic connection of the rod R with the lever B.

The stops S are made adjustable for different widths of strips by means of the details shown in Fig. 3 and Fig. 7. The stops S are mounted upon the bar S through the medium of studs S and springs S which permits the stops S to yield or rotate slightly about the bar S and the stops S to be sensitive to adjustment, as required, as follows:

Underneath stops S and extending across the frame of the machine is a bar E, which is pivoted at its ends to the frame of the ma chine or to the platen P. The pivot-points are indicated by E. Fixed to this bar E there is the lever 111*, which is adjusted by means of the thumb-screw E and spring E causing the bar E to rotate about its pivots, and thereby raise or lower the stops S. The screw E is held by the block E fixed to the bar E fixed to the frame of the machine.

The stops S are connected to a bar S Fig. 13, pivoted at its ends by the pivot-holes S to the under side of the platen P, and the bar S is actuated by means of the cam 8*, connected to bar by means of the roller S arm 8, rod S and link S The cam serves to throw the bar S upward by means of the contact between the link S and the bar, while the weight of the bar causes the bar to descend when the cam permits it.

The clamping-blade Bis mounted in pivots B at the ends of the machine and is actuated by the cam B connected to the shaft 13 through the medium of the roller B rod B and lever B. mit of an adjustment of the connection of the rod B in order to exert more or less pressure in clamping the strip, as is required. The

The lever B is slotted to per-- clamp is released by the spring B connected to the arm B as shown in Fig. 1.

The stop G is composed of an angle-bar g, mounted upon bar G, pivoted at its ends to arms G mounted on a shaft G which is actuated by cam G through the medium of the roller G arm G rod G, and lever G and the spring G returns the parts to their normal position. The bar G is held in its position about its pivots by means of a lever G connected by the screw G to the shaft G the thumb-nut and spring on screw G permitting the required adjustment of the bar G about its pivot to permit a close adj ustment of the angle-bar 9 onto the bender B when the cam is in position for that purpose.

Bender B is mounted in pivots J at the end frames of the machine and is actuated by means of cams J, connected to pivots J through the medium of the roller J arm J chain J and sprocket-wheels Ji fixed to the pivots J, and the bender is returned to its normal position by means of the springs J Any suitable mechanism may be used to perform the functions of actuating the parts, as hereinbefore described; but I prefer to use the mechanism shown.

What I claim is- 1. In a machine of the class described the combination of the shear for cutting the strips from a sheet, adjustable stops for determining the width of the strips to be out, a dis,- charging device for launching the strips forward after the cutting, an intermediate stop for arresting the travel of the strip edge bringing it into alinement, stops for adjusting the position of the strips to be bent with clamping and bending devices and means for automatically actuating the several parts, substantiallyas shown and described.

Y

4. The combination of a feeding-table, of a cuttin g-shear, adjustable stops for regulating the width of the strips to be cut, and a striplaunching device with stops and bending devices for bending the strips, substantially as shown and described.
